Two large semi-precious stones are discovered. A student is asked to find out what material each of the two stones is made of. The student does this by determining the density of the material of each stone. Figure 1 shows the two stones. The student wants to measure the volume of stone A. Stone A cannot be measured using a metre rule as the stone is an irregular shape. Describe how the student could determine the volume of stone A by putting it into water.

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
